The 2-bromo and 2-iodo cations (X = Br, I) are prepared as stable salts 3a and 4a from the title compound (1a).Salt 1a reacts with BaCS3 to yield the new cyclic thiocarbonyl compound (5).Alkylation of 5 with CF3F/AsF5 produces the trithiocarbenium salt (5a).Difluorothiophosgene (7) and its trimer (F3CS)2C=S (8) add to the cation of 1a to form (10a), the perfluorinated analog of 5a.The cation of 10a unlike 5a adds a fluoride ion to give (10), a new isomer of 8.
